The file WoW.mfil in the root directory contains a url made by taking one of the "location" variables and appending the "manifest_partial" to the end of it. If you open that url you actually get a list of the files in the order they're loaded in.

That being said, in my experience every patch is applied in numerical order.

edit: I don't think ladik's mpq editor is actually extracting the patched files even when you open them correctly.

I don't know what other options are available, but if you can figure out how to use stormlib it does work.
